C Code

#include <pro_ext.h>

FAR Example(ParamBlk FAR *parm)
{
#define pFILENAME ((char FAR *) _HandToPtr(parm->p[0].val.ev_handle))

   WHANDLE wh;

   if (!_SetHandSize(parm->p[0].val.ev_handle,
      parm->p[0].val.ev_length+1)) {
      _Error(182); // "Insufficient memory"
   }
   pFILENAME[parm->p[0].val.ev_length] = '\0';

   _HLock(parm->p[0].val.ev_handle);
   wh = _EdOpenFile(pFILENAME, FO_READWRITE);
   _HUnLock(parm->p[0].val.ev_handle);

   _EdSelect(wh, _EdGetLinePos(wh, 12), _EdGetLinePos(wh, 14));
   _EdIndent(wh, 1);
}
FoxInfo myFoxInfo[] = {
   {"EDINDENT", (FPFI) Example, 1, "C"},
};
FoxTable _FoxTable = {
   (FoxTable FAR *) 0, sizeof(myFoxInfo)/sizeof(FoxInfo), myFoxInfo
};
